Abstract (en)
A carburetor (1) comprises: a main barrel (2); a throttle (3) situated in the barrel (2); an idle system which, from a cavity full of fuel, opens into the main barrel (2) through progression and idle mixture holes (14a,14b,15); the idle system comprises elements for metering fuel (17/25) and air (12), which form a primary emulsion. There are several suitably sized passages in the idle system through which the fuel or emulsion flow; the following cooperate with the said passages: first elements (22) for excluding the flow from some of the said passages, keeping at least one (20/31) open to prevent the idle system from emptying during accelerator release; second (EV<sub>1</sub>, EV<sub>2</sub>) organs for positioning the said first elements (22); third devices (5b/7) for recognising accelerator release and checking the said second organs (EV<sub>1</sub>,EV<sub>2</sub>).
